| Outline of Final Research Achievements |
Modeling of the air-sea gas transfer velocity has been investigated by means of numerical simulations, laboratory experiments and field observations. An atmosphere-wave coupled numerical simulation using meteorological and wave models, i.e., WRF and SWAN has been carried out to evaluate the validity of a wave-dependent hybrid model for the gas transfer velocity of carbon dioxide including breaking wind-wave parameters. The results of the mapping of the gas transfer velocity show that such a wave-dependent hybrid model gives a quantitative impact on the evaluation of carbon dioxide exchange across the sea surface. Also, the model expression and the model constants of the hybrid model have been modified on the basis of field observation data.
